Sketcher Einstellungen
Die Einstellungen für den Arbeitsbereich Sketcher befinden sich im Voreinstellungseditor. Im Menü wählt man Bearbeiten → Einstellungen... und dann Sketcher.
Es gibt drei Reiter: Allgemein, Anzeige und Farben.
Allgemein
Auf der Registerkarte Allgemein kann Folgendes festgelegt werden:
Name | Beschreibung |
---|---|
Raster anzeigen | Wenn aktiviert, wird in den Skizzen ein Raster angezeigt.
Diese Wahlmöglichkeit und die folgende 5 Vorzugseinstellungen können auch für nur eine einzelne Skizze im abschnitt Bedienelemente bearbeiten des Sketcher-Dialogs festgelegt werden. |
Rastergröße | Abstand zweier aufeinander folgenden Rasterlinien. Man beachte, dass der Vorgabewert von 0 mm ein Raster mit 10 mm Abstand ergibt. |
Am Raster fangen | Wenn aktiviert, rasten neue Punkte auf der nächstgelegenen Rasterlinie ein. Man beachte, dass sich die Punkte schon dicht an einer Rasterlinie befinden müssen, damit sie einrasten. Der Abstand ist ein Fünftel des Wertes für die Rastergröße, bei einem 10 mm Raster tritt das Einrasten also nur ein, wenn der Punkt nicht weiter als 2 mm von der Rasterlinie entfernt ist.
Note: A snapped point has no coincident constraint with the grid point it snapped to. |
Auto constraints | If checked, the sketcher proposes automatically sensible constraints. If you draw for example a polyline and point towards the bottom, you will see that the sketcher proposes a vertical constraint:. If you set now a point the drawn line segment will get the vertical constraint. |
Avoid redundant auto constraints | If checked, the sketcher tries not to propose redundant auto constraints. This option only has an effect if also the option Auto constraints is used. |
Rendering order | The order how sketches are rendered. To change it, drag and drop one of the geometries to the top or bottom. |
Show Advanced Solver Control in the Task bar | If checked, the sketcher dialog will have the additional section Advanced solver control to adjust solver settings. |
Improve solving while dragging | If checked, a special solver algorithm will be used while dragging sketch elements. This avoids that the sketch flips around while dragging. It is an improvement for most cases, however for complex sketches this option can increase the time to solve the sketch. |
Auto remove redundants | TBD |
Esc can leave sketch edit mode | If checked, Esc key will trigger exiting sketch editing mode. The option to disable this may be useful for users who are used to pressing Esc as part of their workflow in other CAD solutions but don't necessarily want to exit a sketch. |
Notify automatic constraint substitutions | If checked, you will be informed with a dialog about constraint substitutions. For example if the endpoints of two arcs are connected with the coincident constraint and you reconnect the arcs using the tangent constraint, the coincidence constraint will be substituted by the tangent constraint and you will get a popup dialog to telling you this. |
Anzeige
In the Display tab you can specify the following:
Name | Description |
---|---|
Font size | The font size used for the labels and constraints in the sketch. |
Grid line pattern | The line pattern used for grid lines. Grid lines will be displayed if you set the option Show grid. |
Segments per geometry | Curves are approximated by polygon segments for visualization. The segments per geometry define the number of polygons for the approximation. The lower limit are 50 segments. Higher values refine the visualization but can lead to longer calculation times, especially for B-splines. |
Ask for value after creating a dimensional constraint | If checked, a dialog will pop up to input a value for new dimensional constraints. |
Geometry creation "Continue Mode" | If checked, the current sketcher creation tool will remain active after the creation. If you use for example the line tool , it will remain active after you created a line with it. You can leave the tool any time by right-clicking into the sketch. |
Constraint creation "Continue Mode" | If checked, the current constraint creation tool will remain active after the creation. If you use for example the tangent tool , it will remain active after you created a constraint. You can leave the tool any time by right-clicking into the sketch. |
Hide base length units for supported unit systems | If checked, base length units will not be displayed in the sketch constraints. The actual base length unit is the one of the selected unit system. |
Use Diameter as default constraint for arcs and circles introduced in version 0.20 | If checked, diameter will be used as default constraint for arcs and circles instead of radius. |
Hide all objects that depend on the sketch | If checked, all features that depend the sketch will be hidden when the sketch is opened. Note that the effect of this option might not occur when using the option Show objects used for external geometry and/or Show object(s) sketch is attached to. |
Show objects used for external geometry | If checked, all objects used for an external geometry will be shown. If you edit for example a sketch that uses the geometry of a pad, this pad will be shown (if not already). Other features in the model tree between the pad and the sketch will not necessarily be shown. |
Show object(s) sketch is attached to | If checked, objects the sketch is attached to will be shown when the sketch is opened. If you attached for example a sketch to a pocket, this pocket will be shown (if not already). Otherwise you will only see the sketch if the pocket was not shown in advance. |
Restore camera position after editing | If checked, the camera position is moved back to where it was before sketch was opened. |
Force orthographic camera when entering edit introduced in version 0.20 | If checked, camera mode will be forced to orthographic when opening a sketch for edit. Camera mode will be restored when leaving edit mode. This preference is available only if Restore camera position after editing is activated. |
Open sketch in Section View mode introduced in version 0.20 | If checked, when editing a sketch, it will by default open with 'Section View' active. |
Apply to existing sketches | If pressed, the options in the preferences section Visibility automation will be applied to existing sketches too. Otherwise these settings will only be used for new sketches. |

Fully constrained edit vertex color | Color of fully constrained vertex (point) color |
Constraint color | Color of driving constraints, except of dimensional constraints that get the Dimensional constraint color. |
Reference constraint color | Color of reference constraints |
Expression dependent constraint color | Color of expression dependent constraints |
Deactivated constraint color | Color of deactivated constraints |

Coordinate text color | Text color of coordinates |
Cursor crosshair color | Color of crosshair cursor. This is the one you get when creating a new sketch element. |
Hint: The color for selections inside sketches is the global selection setting Enable selection highlighting, see the Preferences Editor.

Note
There is another preference that has an influence on sketches. If the Transparent objects preference on the Display → 3D View tab is set to Backface pass
, the arrowheads on one end of sketcher dimensions are hidden if Show grid is deactivated in the Edit controls section of the Task panel. This applies to FreeCAD version 0.19, version 0.20 and recent development versions (up to 0.21-30058, at least) except Link branch.
Front view, grid enabled and grid disabled
Rear view, grid enabled and grid disabled hiding arrowheads on the opposite end as well as the dimension value
